REFERENCE TO THE RELATED APPLICATION AND PRIORITY CLAIM

This application is a continuation of U.S. patent application Ser. No. 15/835,083, filed Dec. 7, 2017, which claims priority to TW Application Serial No. 105140693, filed Dec. 8, 2016, both of which are hereby incorporated in their entirety by reference.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a login mechanism, and in particular, to a login mechanism for an operating system.

Description of the Related Art

In the current era of rapid development of science and technology, computers (for example, desktop computers or notebook computers) already become one of the essential electronic products in companies, schools, shopping malls or families. Highly private personal data or confidential information may be stored in a computer. Therefore, an existing computer provides a login mechanism using password authentication. A user needs to enter a correct login password to log in to a computer and perform an operation, so as to maintain the information security of the computer.

Nowadays, phishing programs and computer viruses are highly rampant. Once a user is incautious, a backdoor program (for example, a Trojan horse) is planted in a computer very easily. As a result, a login password for the computer is logged and stolen by a malicious person such as a hacker. Personal data or confidential information stored on the computer further leaks consequently, or even the control right of the computer is acquired by the malicious person. As can be seen, nowadays, a login mechanism using a password to authenticate a user can no longer provide a computer with sufficient security.

In view of this, many companies and enterprises require an employee to change a login password periodically, and a changed login password cannot be the same as a previous login password, so as to prevent login by a malicious person, thereby improving the strength of information security of the computer. However, when logins are frequently changed, it is difficult for an employee to memorize a login password for a computer. Often, an employee repeatedly enters incorrect login passwords to lock a computer, and an information security department of a company needs to engage to unlock and allocate a new login password, causing unnecessary trouble for the information security department. Moreover, a fairly old or lazy employee may even write down a login password on a piece of paper for convenient login. As a result, a login password leaks easily, the information security of the employee's computer is severely jeopardized, and a mechanism of authenticating user identity by using a login password is practically neutralized. Further, it becomes meaningless to use a login password to authenticate user identity to ensure the information security of a computer.

In view of the above, many companies and enterprises allocate unique login credentials generally in a card form to each employee. When an employee logs in to a computer, the computer needs to authenticate the login credentials to ensure that the employee is a valid user of the computer. However, in such a login mode, an additional authentication system needs to be established, and additional costs are needed to make login credentials of the employees. Considerable time and expense are needed for subsequent maintenance and update of the authentication system and login credentials. This login authentication mode is hardly desirable for companies or enterprises.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a login mechanism for an operating system, so as to improve the convenience and security of logging in to a computer operating system.

Another object of the present invention is to provide a login mechanism for an operating system, so as to perform login by using a mobile device.

Still another object of the present invention is to provide a login mechanism for an operating system, so as to automatically generate a new login password for a computer operating system.

A login mechanism for an operating system provided in the present invention includes:

a computer device, including a processing unit and a transmission unit, the computer device being loaded with a computer operating system; and

a mobile device, including: an operation unit, an information transmission unit, and a sampling unit, the information transmission unit being capable of transmitting a login password, and the sampling unit verifying a human biometric feature, where

when login needs to be performed to the computer operating system, the sampling unit of the mobile device verifies a biometric feature of a user, and after verification succeeds, the information transmission unit transmits the login password to the transmission unit of the computer device, so as to log in to the computer operating system.

Preferably, the mobile device further includes a password generation application. The password generation application is capable of generating a new password. The new password is used to update an authentication password on the mobile device and is capable of being transmitted to the computer device, to update a verification password on the computer device.

Therefore, in the present invention, a mobile device stores a login password for a computer operating system. Before operating a computer device, a user needs to first pass biometric feature authentication of the mobile device. After the biometric feature authentication succeeds, the mobile device transfers a password to the computer device, to enable the user to enter the computer operating system of the computer device for the user perform an operation. In this way, a user does not need to choose a password to enter, so as to avoid an embarrassing situation in which the user forgets a password and consequently cannot enter the computer operating system of the computer device to operate the computer device, and the user only needs to pass the biometric feature authentication of the mobile device to log in to the computer operating system, so that the convenience of login by the user is improved. Next, in the login mechanism of the present invention, two-factor authentication including login password authentication and biometric feature authentication is used to protect the security of a user account. In the login mechanism, both the mobile device that stores a login password and a user that can pass biometric feature authentication are required to log in to the computer operating system, so that the security of an account is greatly improved. Moreover, the login mechanism of the present invention may adapt to an existing login mechanism for a computer operating system, and in the login mechanism, an authentication system does not need to be additionally established or login credentials do not need to be additionally made. In this way, information security costs of companies or enterprises can be reduced, and the management convenience of information security departments is improved. Furthermore, the mobile device of the present invention may automatically generate a new login password, and the new login password may be directly written over a login password in the computer operating system of the computer device. In this way, not only information security requirements of information security departments of companies or enterprises can be satisfied, but also leakage of information that occurs because an original password is stolen by a malicious person such as a hacker can be avoided, thereby improving the security strength of information.

When the biometric authentication information 381 is consistent with the biometric verification information 342, the verification program 50 enables the information transmission unit 36 to transmit the authentication password 341 to the transmission unit 28 of the computer device 20.

After the transmission unit 28 of the computer device 20 receives the authentication password 341, the authentication program 40 on the computer device 20 enables the processing unit 22 to compare the authentication password 341 with the verification password 261 in the first storage unit 26. When the authentication password 341 is consistent with the verification password 261, login may be performed to the user account in the computer operating system 25, so that the processing unit 22 executes the computer operating system 25.

Therefore, in the login mechanism of the present invention, a login password for a user account in a computer operating system of a computer device is stored in advance in a mobile device. When wanting to log in to the user account, a user first passes identity authentication of the mobile device. The mobile device then transmits the login password to the computer device and login may be performed to the user account. In this way, the user does not need to remember a login password and may log in by simply passing biometric feature verification of the mobile device, thereby significantly improving the convenience of logging in to the user account on the computer device.

It should be noted that after the mobile device 30 and the computer device 20 are bound, the user may perform binding management between the mobile device 30 and the computer device 20 by using the binding management button 423 on the function selection page 42 of the authentication program 40 on the computer device 20, or may set various parameters of the authentication program 40 by using the setting button 424 on the function selection page 42.

When the user wants to update a password of the user's user account, referring to FIG. 12 and FIG. 18, the user taps the password update button 421 on the function selection page 42 on the operation interface 41 on the computer device 20. The authentication program 40 on the computer device 20 transfers a password generation request 402 to the verification program 50 on the mobile device 30 by using the transmission unit 28 and the information transmission unit 36 of the mobile device 30. Referring to FIG. 16 and FIG. 19, after the verification program 50 on the mobile device 30 receives the password generation request 402, the identity verification prompt 56 pops up on the control interface 52 of the verification program 50. The user provides a biometric feature such as a fingerprint or face to be sampled by the sampling unit 38. The operation unit 31 then compares the biometric authentication information 381 generated by the sampling unit 38 with the biometric verification information 342 in the second storage unit 34. When the biometric authentication information 381 is consistent with the biometric verification information 342, the verification program 50 starts the password generation application 51. The password generation application 51 generates a new password. The new password is a new login password 511 for the user account in the computer operating system 25. The new login password 511 is written over the authentication password 341 in the second storage unit 34 of the mobile device 30, so as to update the authentication password 341. The new login password 511 may alternatively be written over the verification password 261 in the first storage unit 26 of the computer device 20 by using the information transmission unit 36 of the mobile device 30 and the transmission unit 28 of the computer device 20, so as to update the verification password 261. After updating a login password, the user may confirm the updated login password, for example, efgh shown in FIG. 20, by using an account information page 56 of the verification program 50 on the mobile device 30.

It should be noted that, all information transferred between the transmission unit 28 of the computer device 20 and the information transmission unit 36 of the mobile device 30 is encrypted by the first encryption/decryption unit 29 or the second encryption/decryption unit 37, to ensure that the information is perfectly secure during transmission.

It may be understood that the mobile device of the present invention 30 may be bound to multiple user accounts in the computer operating system 25, and one user account in the computer operating system 25 may be bound to multiple mobile devices 30. The present invention is not limited to a case in which one mobile device 30 can only be bound to one user account.

The login mechanism of the present invention may adapt to an existing login mechanism for a computer operating system. A user only needs to respectively install a verification program and an authentication program of the present invention on a mobile device and a computer device before the mobile device can store a login password for the computer device and perform identity authentication, and an authentication system does not need to be additionally established or login credentials do not need to be additionally made. In this way, information security costs of companies or enterprises can be reduced, and the management convenience of information security departments is improved. Next, in the login mechanism of the present invention, two-factor authentication including login password authentication and biometric feature authentication is used to protect the security of a user account. A person who wants to log in to an account needs to first obtain a mobile device that stores a login password for the account and pass biometric feature authentication of the mobile device to enter and use the account, so that the security of the account is greatly improved. Moreover, the mobile device of the present invention stores a login password for the computer operating system of the computer device, so that the mobile device become an authenticator for the computer operating system. The mobile device only needs to authenticate the biometric feature of the user before the user can log in to a user account in the computer operating system by using the mobile device. In this way, an embarrassing situation in which the user forgets a password and consequently cannot enter the computer operating system to operate the computer device can be avoided. Biometric feature verification may further be used to ensure that a person who wants to perform login is a valid user. Furthermore, the login mechanism of the present invention may automatically generate a login password for the computer operating system, and the new login password may be directly written over a login password in the computer operating system. In this way, not only information security requirements of information security departments of companies or enterprises can be satisfied, but also leakage of information on the computer device that occurs because an original login password is stolen by a malicious person such as a hacker can be avoided, thereby improving the security strength of information.
